+# Google Cloud 
+
+With the introduction of the Kubernetes Gateway API it is now possible to use Argo Rollouts with all compliant implementations that support it. The integration is happening with the plugin currently hosted at Argo Labs.
+
+Useful resources:
+
+* [The Gateway API specification](https://gateway-api.sigs.k8s.io/)
+* [Support of the Gateway API in Google Cloud](https://cloud.google.com/kubernetes-engine/docs/concepts/gateway-api)
+* [Argo Rollouts Plugin capabilities](../plugins/) 
+* [Plugin for the Gateway API](https://github.com/argoproj-labs/rollouts-plugin-trafficrouter-gatewayapi)
+
+The process involves the following steps:
+
+1. Creating a Kubernetes cluster with support for the Gateway API in Google Cloud
+1. Creating a Load balancer that is managed by the Gateway API in Google Cloud
+1. Installing Argo Rollouts + gateway API plugin in the cluster
+1. Defining a Rollout that takes advantage of the plugin
+
+For a full application that includes all manifests see the [plugin example](https://github.com/argoproj-labs/rollouts-plugin-trafficrouter-gatewayapi/tree/main/examples/google-cloud).
